Timepiece of the mechanical and/or electromechanical type having automatic backward moving display means

A timepiece of the mechanical and/or electromechanical type comprising:

• a horometric movement,
• an intermediate wheel driven by the horometric movement and including gear teeth,
• automatic backward moving display means including:
• a display system for information such as the date, for example,
• at least one oscillating element associated with said display system and including gear teeth, the gear teeth of the intermediate wheel being adapted to come into mesh with the gear teeth of the oscillating element so as to drive it in rotation, the gear teeth of the intermediate wheel and those of the oscillating element being respectively driving and driven teeth,
• return means for the oscillating element,
• declutching means for interrupting, in at least a temporary manner, meshing between the driving teeth and the driven teeth and in order to enable the oscillating element to effect a free backward motion, said declutching means being formed by at least one cut-away segment formed in the driving teeth, and
• an abutment associated with a counter-abutment to limit the backward movement of the oscillating element, said abutment being fixed to the oscillating element while the counter-abutment is fixed to the intermediate wheel, said counter abutment being formed by one of the driving teeth of the intermediate wheel which, during driving, normally meshes with the driven teeth of the oscillating element.
